Cross-Platform Compatibility Guide

You are providing cross-platform guidance. Follow these steps:

1. Query

The user needs help with: $ARGUMENTS

2. Read Documentation

Read the cross-platform documentation: skills/terminal-docs/references/13-cross-platform.md

Also relevant:

• skills/terminal-docs/references/12-windows.md

3. Key Differences

Line Endings

Platform	Ending
Unix/Linux/macOS	LF (\n)
Windows	CR+LF (\r\n)

Path Separators

Platform	Path	PATH
Unix	/	:
Windows	\	;

Environment Variables

Purpose	Unix	Windows
Home	$HOME	%USERPROFILE%
Temp	$TMPDIR	%TEMP%
User	$USER	%USERNAME%

4. Common Patterns

Portable Path Handling (Python)

from pathlib import Path
path = Path('dir') / 'subdir' / 'file.txt'

Color Support Detection

def supports_color():
    if os.environ.get('NO_COLOR'):
        return False
    if not sys.stdout.isatty():
        return False
    return True

Terminal Size

import shutil
size = shutil.get_terminal_size(fallback=(80, 24))

5. Provide Response

Based on the user's query:

1. Identify the cross-platform concern
2. Show platform-specific implementations
3. Provide portable abstraction code
4. Note edge cases and gotchas
5. Recommend cross-platform libraries if applicable
